Commissioning
(Addressing)
To be able to setup, configure, and have it communicate with other devices on
a segment, a device must be assigned a permanent address. Unless
requested otherwise, it is assigned a temporary address when shipped from
the factory.
If there are two or more devices on a segment with the same address, the first
device to start up will use the assigned address (ex. Address 20). Each of the
other devices will be given one of the four available temporary addresses. If a
temporary address is not available, the device will be unavailable until a
temporary address becomes available.
Use the host system documentation to commission a device and assign a
permanent address.
